Prosecutors decline to charge man held in killing of 1-year-old Autumn Johnson

Los Angeles County prosecutors on Wednesday declined to file charges against a 23-year-old man arrested earlier this week on suspicion of killing 1-year-old Autumn Johnson in Compton, a district attorney's spokeswoman said.

Prosecutors have "asked for further investigation from the investigative agency," spokeswoman Sarah Ardalani said in an email. Ardalani said the office would not comment further.

Ray Howard Patterson was taken into custody Monday in Compton by sheriff's investigators. Authorities said detectives suspected him of being the gunman in the child's killing, which drew widespread outrage. He was released Wednesday evening.
